Abstract
BACKGROUND "Slow flow" is one very important concept in modern fundamental and clinical biomedicine. Slow coronary flow is indicative of delayed filling of the terminal coronary artery vessels, occurring in the absence of significant coronary stenosis. This group patient of patients exhibits a high incidence of disability and represents a significant financial and material burden for the state and the healthcare system in general. OBJECTIVE The primary objective of our study was to examine patients with slow coronary flow. METHODS We studied the standard parameters recommended by the international health care system (electrocardiography (by Medica QRS-12, Germany), through the electrical activity of a patient's heart by the electrical impulses (beating) of the heart; HC1(Germany); coagulogramma by Coatron M1 (Germany), troponin by AQT 90 (Germany); general blood test we used automatic human counting device HC1(Germany). Also, we investigate the original parameters (non-standard parameters, which we use in this pilot study) that we were first studied for this diagnosis and non-standard parameters. RESULTS A general blood test showed that patients with slow flow had a higher blood leukocyte count than the control group, but the amount of hemoglobin was normal, the hematocrit was much higher than in the control group, and the platelet count was close to the lower limit of clinical standards.We obtained details of blood flow by coagulation situation, such as prothrombin time, prothrombin index, international normalized ratio, activated partial thromboplastin time, thrombin time, fibrinogen, and rheological properties such as index of erythrocyte aggregability, index of erythrocyte deformability, plasma viscosity, in silico blood rheological index. CONCLUSSION Blood flow can be considered as a superposition of vortices with similar frequencies and wave vectors that change after bifurcations or other obstacles in the vascular network. These factors together determine the conditions for structuring the flow of moving blood. Disruption or alteration of these factors results in slow flow. It has been found that the speed of blood flow in the coronary arteries depends on changes in the number and function of red blood cells. Slow flow is directly influenced by the aggregation and deformation of red blood cells, their number, and plasma viscosity. Consequently, the rheological status plays a crucial role in determining blood flow and its velocity.

Eosinophil Recovery Time Is Associated with Clinical Outcomes in Patients with Type A Acute Aortic Dissection: a Retrospective Cohort Study. J Cardiovasc Transl Res 2024; 17:723-731.

Abstract
Type A acute aortic dissection (TA-AAD) patients are prone to life-threatening complications and death. This study aimed to analyze the association between eosinophil (EOS) recovery and clinical outcomes in TA-AAD. A total of 274 patients with TA-AAD were eligible for inclusion, and 54 patients died within 1 month. The patients with poor clinical outcomes showed significantly lower EOS count within 8 days after surgery. The time-dependent ROC analysis showed that EOS recovery days predicted 1-month death with an AUC of 0.886 and a cutoff of 6 days. EOS recovery within 6 days was associated with a lower incidence of postoperative infection, a poorer prognosis, and a lower risk of 1-month and 6-month mortality than those requiring more recovery days. Collectively, postoperative early recovery of EOS predicted lower mortality and better prognosis and may be applied as an effective, rapid, and simple tool for the risk stratification and prognostic prediction of patients with TA-AAD.Clinical trial registration number: NCT05409677.

Abstract
Coronary slow flow is taken to be indicative of delayed filling of terminal vessels of the coronary arteries in the absence of coronary stenosis, as detected using coronary angiography. Patients suffering from coronary slow flow typically experience recurrent chest pain, thereby markedly affecting their quality of life. The etiology and pathogenesis of coronary slow flow, which is gradually attracting clinical attention, have yet to be sufficiently established, although it is currently believed that they may be associated with endothelial dysfunction in the coronary arteries, inflammatory response, abnormalities in microvascular reserve function, subclinical atherosclerosis, blood cell and platelet abnormalities, and genetic factors. In this review, we provide a brief overview of recent progress in research on the pathogenesis of coronary slow flow with a view toward elucidating the possible underlying pathogenesis and identify targets and directions for the treatment of this condition.

Animal Model Exp Med 2022; 5:470-481.

Abstract
The association between blood eosinophil (EOS) counts and arterial/venous thrombosis is unclear. We aim to explore whether EOS count is a risk factor for thrombosis. We searched several databases and preprint platforms using core terms ‘eosinophil’, ‘myocardial infarction’, ‘ischemic stroke’, and ‘venous thromboembolism’ (VTE), among others. Studies comparing the odds ratios (ORs) or risk ratios (RRs) of EOSs with the abovementioned diseases were eligible. Overall, 22 studies were included. A high EOS count was associated with acute coronary artery thrombosis events (OR: 1.23, 95% CI: 1.15–1.32), short‐term cerebral infarction and mortality (RR: 2.87, 95% CI: 1.49–5.51). The short‐term risk of VTE was more common in patients with EOS‐related diseases (RR: 6.52, 95% CI: 2.42–17.54). For coronary artery disease, a high EOS count was a protective factor against 6‐month to 1‐year mortality (RR: 0.56, 95% CI: 0.45–0.69) but was associated with long‐term mortality (RR: 1.64, 95% CI: 1.25–2.14). Therefore, we conclude that for coronary artery thrombosis, EOS count is not associated with AMI events in general population. It may be associated with NSTEMI and STEMI in CAD patients, but more studies are needed to confirm this. In addition, EOS count is associated with an increased risk of both short‐ and long‐term mortality but is not predictive of the composite endpoints. For cerebral artery thrombosis, EOS count may be associated with cerebral infarction and could lead to an increased risk of poor short‐term prognosis. For VTEs, EOS count was a risk factor for some patients, especially those with acute‐phase EOS‐related diseases.

Abstract
Background The relationship between increased mean platelet volume (MPV) and atherosclerosis is well known. In the present study, MPV in patients with coronary slow flow (CSF) and in cases with normal coronary anatomy (NCA) was investigated and compared with the aim of identifying the relationship between CSF and MPV. Patients and methods We studied 40 patients previously determined via coronary angiography as having NCA and 40 patients with CSF in the coronary blood stream, as identified by thrombolysis in myocardial infarction square. Thus, a total of 80 patients from the Elaziğ Education and Research Hospital (Elaziğ, Turkey) were included in the present study retrospectively and laboratory and anamnesis information was scanned into their files. The relationship between MPV and CSF was studied. Results MPV levels were observed to be significantly higher in the CSF group compared to the NCA group (10.05±1.3 and 8.6±0.6, p<0.001). In receiver operating characteristics analyses, it was determined that an MPV >9.05 measured in CSF patients at application had a predictive specificity of 77.5% and sensitivity of 77.5% for CSF (area under the curve: 0.825, 95% confidence interval [CI]: 0.726–0.924, p<0.0001). It was found that MPV level was an independent predictor of CSF (β=−600, p<0.001, 95% CI: −0.383 to −0.176). Conclusion MPV is increased in patients with CSF when compared to patients with NCA. This finding supports the fact that MPV could be a predictor of CSF.

Abstract
PURPOSE Mean platelet volume (MPV) and neutrophil to lymphocyte ratio (NLR) are the new markers of the detection of inflammation. Our aim is to investigate MPV and NLR in lean and obese patients with polycystic ovary syndrome (PCOS). METHODS This study was designed to investigate MPV, NLR, and high-sensitive C-reactive protein (hsCRP) levels in 25 obese patients with PCOS and 16 lean patients with PCOS, and our study group was matched with 16 obese and 14 non-obese controls, respectively. RESULTS PCOS group had higher MPV, NLR, neutrophil count, neutrophil to total leucocyte ratio, basophil count, waist circumference (WC), insulin, glucose, and HOMA-IR rates than those of controls. hsCRP levels were similar in both groups. Subgroup analyses revealed that obese PCOS group had higher insulin and HOMA-IR levels, compared to those of controls. In this subgroup, total leucocyte counts, MPV, and hsCRP levels were similar. On the other hand, lean PCOS group had higher WC, NLR, MPV, and basophil count than controls. In correlation analysis, hsCRP was positively correlated with body mass index (BMI), WC, total leucocyte count, neutrophil count, while negatively correlated with lymphocyte ratio. Although leucocyte count was positively correlated with BMI, MPV was negatively correlated with BMI, total leucocyte, platelet, and neutrophil counts. NLR was positively correlated with HOMA-IR, hsCRP, BMI, WC, and insulin. CONCLUSION Our study demonstrated that MPV and NLR levels are increased despite similar hsCRP levels in patients with PCOS. However, we failed to demonstrate these differences in obese PCOS patients. Further studies with larger sample size are required to determine the significance of BMI in the inflammation of PCOS patients.
